In the study the following nomenclatural problems were solved: Mucor cylindrosporus Ling-Young, M. dimorphosporus Lendn., M. oudemansii Váňová, nomen novum, M. sciurinus Naumov and M. wosnessenskii Schostak. The following new combinations were realized: Mucor dimorphosporus Lendn. f. sphaerosporus (Hagem) Váňová, Mycocladus blakesleeanus (Lendn.) Váňová, Mycocladus corymbijer (Cohn in Lichth.) Váňová and Mycocladus ramosus (Zopf in Schenk) Váňová. Finally, the Latin diagnosis of the taxon Micromucor ramannianus (Moeller) v. Arx var. angulisporus Naumov ex Váňová was completed.
